Sober Virus Clones Taunt AV Vendors

In the latest attack, F-Secure researcher Alexey Podrezov said the virus writers left a message in the code that taunts anti-virus vendors.

"This time the author of Sober worm changed the encryption algorithm for text strings in the worm's body. And he included a message for anti-virus vendors in the worm's body basically saying that 'Use your debuggers, it's fun,'" Podrezov said in an advisory.
